Application filed February 13, 1911.

To all whom it may concern Be it known thatI, FREDERIG E. BAGER, acitizen of the United States of America, and resident of SouthMilwaukee, Milwaukee county, "Wisconsin, have invented a certaln new anduseful Improvement in Bank-Spuds for Barges or the like, of which thefollowing'is a specification.

My invention relates to what are known as spuds for barges orotherboats.

It relates more particularly to the kind of spuds that are adapted toengage the banks of a stream or channel to hold the barge or other boatstationary. This is necessary, for example, in dredging, as in such casethe barge or boat must be heldfirmly in a fixed position. Often this canonly be done satisfactorily, when the stream or channel is narrow, byspuds that 1 engage the banks. Prior to my invention the differentarrangements for doing this were not always satisfactory. My inventioncontemplates, therefore, a barge or boat upon which the spuds arearranged horizontally, and in which mechanism is employed for operatingthe spuds either separately or simultaneously, each spud being provided,if desired, at its end with a movable shoe or plate that engages thesloping bank of the stream or channel, whereby the barge or boat is notonly heldstationary during the time that the dredge or excavator thereonis doing the required work, but is also maintained at a point'midwaybetween thetwo banks, without having the tops of the spuds mterfer withthe operation of the dredge or excavator, as will hereinafter more:fully appear.

To these and other useful ends my inven tion consists in mattershereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a side elevation ofa dredge orexcavator barge provided with bank spuds, and means for operating thesame, embodying the principles of my invention. Fig. 2 is a plan, on asmaller scale, of the barge or boat shown inFig. 1. Fig. 3 is across-section on line 33 in Fig. 2.

As thus illustrated, the barge or boat A may be of any suitable ordesired character. The excavator car or body B is mounted on aturn-table G disposed centrally of the deck ofsaid barge or boat. At thecenter Specification of Letters Patent.

Serial No. 608,404.

of said turn-table there is located a vertically disposed shaft 0 whichhas its upper end suitably connected with the engine D, whereby theshaft-may be rotated at will. The said .shaftis provided with sprocketwheels 0 and 0 at the lower end thereof, andthese are connectedrespectively by chainso and 0* with the short vertical shafts a and-awhich are located at opposite ends of the said-barge orboat; These shortshafts are providedwvith pinions a anda which en-.

gage the racks a and a, the racks a being parallel and disposedatoppositesides ofthe pinion a and the: racks a being arranged; insimilar-relation to the'pinion a whereby all of said racks are disposedtransversely of the boat or barge. Eachrack is secured'to horizontallyand transverselydisposed spuds E, which latter are mounted to slideinthe bearings esecured to the top of the deck of said barge or boat,each spud being provided at its outerend with a shoe-or plate 6 which ispivoted at c to enable it to automatically adjust. itself to the slopeor angle of the bank. These spuds, therefore, are mounted horizontally.upon the deck of the barge or boat, and are adaptcdto be moved in andout by the sprocket chain transmission pre viously described.

From the foregoing itwill be seenthat I provide an improved bank spudarrangement which will not only hold the boat or bargestationary whilethe excavator or dredge is performing the desired operation, but'whichwill also maintain the said barge or boat at the'center of the stream orchannel in which it is operating, without in any way mutilating ortearing up the banks thereof. The said spuds are easily controlled,regardlessv of the position of the excavator car orbody on theturn-table, because the shaft from which the 'spnds are controlled islocated at the axis of said turntable, whereby the position of the saidhousing or excavator body does not in any way affect the operativenessof the said transmitting connection by which the engine or other motivepower of the excavator is employed for forcing the spuds against thebanks, and for then withdrawing them when it is necessary to move theexcavator or dredge to some other point in the stream or channel inwhich it is operating. As the spuds operate horizontally, when thrustagainst the banks, they do not tend to lift the barge or boat out of thewater. Also, as they have a long reach sidewiso from the boat againstthe banks of the stream or channel, they give the excavator or dredge agreater degree of stability, and prevent it from tilting sidewise whenthe housing or body is swung around on the turn-table. As they arehorizontal, the tops of the spuds do not interfere with the operation ofthe dredge or excavator. For example, the spuds are always so entirelyout of the way that they never interfere with the rotation of the body Bon the turntable.

What I claim as my invention is 1. In a barge or boat, bank spuds therefor, arranged horizontally upon the deck thereof at opposite sides ofthe boat, and means for operating said spuds, the spuds at one sidebeing opposed by those at the other side, and excavating apparatusmovable freely around above said spuds.

2. In a barge or boat, bank spuds therefor, arranged horizontally uponthe deck thereof, means for operating said spuds, said means comprisingracks secured to the spuds, pinions engaging said racks, and means belowsaid deck for operating the pinions about vertical axes.

3. In a barge or boat, bank spuds therefor, arranged horizontally uponthe deck thereof, means for operating said spuds, said means comprisingpinions rotatable aboutvertical axes, means for operating said pinionsin unison, and parallel racks disposed at opposite sides of each pinion,whereby each pinion is engaged by two racks, each rack being secured toone of said spuds.

4. In a barge or boat, bank spuds therefor, arranged horizontally uponthe deck thereof, means for operating said spuds, said means comprisingracks and pinions for operating said spuds in unison, a centrallyarranged shaft having suitable connection with said pinions, aturn-table having the said shaft located at the axis thereof, a body onsaid turn-table, and means on said body for operating said shaft.

5. In a barge or boat, .bank spuds therefor, arranged horizontally uponthe deck thereof, means for operating said spuds endwise, said spudsbeing all arranged in the same horizontal plane, and each spud beingprovided with a pivoted shoe or plate for engaging the banks of thestream or channel in which the barge or boat is floating, there being aplurality of said spuds at each side of the boat, the spuds at one sidebeing opposed by those at the other side, and excavating apparatusmovable freely around above said spuds.

6. In a barge or boat, bank spuds therefor, arranged horizontally uponthe deck thereof, means for operating said spuds, said spuds beingarranged in pairs at opposite ends of the barge or boat, the members ofeach pair being provided with a single operating device.

7. The combination of a barge or boat, spuds for said barge or boatdisposed horizontally thereon, a movable member on said barge or boat,said member arranged to move over said spuds, mechanism on said memberfor controlling 'said spuds, and a power transmitting connection betweensaid spuds and mechanism, disposed in position not to interfere with orbe injuriously affected by the movements of said member, whereby saidspuds are operable in any position of said body.

8. The combination of a barge or boat, horizontal spuds therefor, amovable body on the barge or boat, mechanism for operating said spudshorizontally in a plane below said body, and means on said body forcontrolling said mechanism.

9. A barge or boat, an excavator or dredge body movably mounted on saidbarge or boat, and horizontal spuds between the bottom of said body andthe deck of said barge or boat, projecting laterally therefrom, togetherwith means on said body for controlling said spuds.

10. A barge or boat, an excavator or dredge body movably mounted on saidbarge or boat, and horizontal spuds between the bottom of said body andthe deck of said barge or boat, projecting laterally therefrom, togetherwith means below the said deck for connecting and operating said spuds.
